Advice for a DIY fruit cage?

Thanks, very much, JJB. And yes, I did forget to mention the hinged door in my fit of optimism...I think that would be necessary for what I'm envisioning.

Veggie, we have currants, raspberries, boysenberries, and strawberries. I even wondered about relocating the dwarf cherry tree to that area as it will be a few years before it's too big and I might get to eat one cherry in that time And then I might be inspired to actually buy a couple of potted blueberry plants. Between the birds and the baby and dry spring, I hardly got any strawberries this year!
